1. The main body of the electromagnetic heater is a rod-type reciprocating tubular structure, which is made by welding a ferromagnetic heat-carrying rod body, a steel sleeve and a high-strength flange. After advanced welding process, the main body of the heater has the characteristics of high pressure resistance, strong sealing, strong thermal strain capacity and corrosion resistance, and can withstand sufficient mechanical pressure and strength.
2. The electric heating control cabinet used in conjunction with the electromagnetic heater is a cabinet-type protective structure, which is formed by bending and welding of high-quality thick steel plates. The shell is treated by electrostatic spraying anti-corrosion process. The cabinet is composed of leakage air switch, AC contactor, temperature control instrument, reactive power compensation element, overheating protection relay and other devices. The control circuit device has a master switch, which can manually input and cut off the power supply of the control circuit.
3. According to the place of use, the electric heating control cabinet used in the electromagnetic heater is divided into two specifications: general protection type and explosion-proof type; the heating method is divided into power frequency electric heating type and constant temperature variable frequency electric heating type, which can be applied to different Heating process and place of use.
